BAG HOLDER.

Specification of Letters Patent.

Patented May 16, 1922.

Application filed March 6, 1919. Serial No. 281,050.

To all whom it may concern Be it known that I, J GEN S'runnoox, asubject of the King of Great Britain, residing at Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Bag Holders, of which the following is a full, clear,and exact specification.

This invention relates to bag holding means and more particularly to thetype of bag holder used in supporting large fabric bags upon threshingmachines and machines of like character, and in a position to be filledwith grain.

The object of the invention is to provide bag supporting and holdingmeans for firmly and securely holding the bag in position to receivegrain and other material dis charged from a chute, and also to providemeans whereby the bag may be easily and quickly released when the baghas been filled.

A further object is to provide bag releasing means which may be operatedwithout any material effort on the part of the operator and without thenecessity of lifting the bag 011 the support.

WVith these objects in view I have illus trated in the accompanyingdrawing one practical embodiment of the invention, and,

Figure 1 illustrates the improved con-- struction in plan View;

Fig. 2 is a side elevation of the construe tion shown in Fig. 1;

Fig. 3 is an enlarged detail view illustrating the bag holding orpiercing means, and the means for reciprocating the bag piercing means;

Fig. 41 is a vertical section taken 011 line 4-4. of Fig. 3, looking inthe direction of the arrows.

Figure 5 is a detail view taken on the line 5-5 of Fig. 1 showing theslot in the main frame and the handle mounted therein; and Fig. 6 is adetail view taken on the line 6-6 of Fig. 1. showing the means forsupporting the ring on the main frame.

The support 10 for the bag holding means I is stationary, and in apractical embodiment will probably form a part of the machine frame.This support is provided with a pair of outwardly extending brackets 11,each of which is provided with an offset lug 12, these lugs formingrests for the frame of the bag holding means in its operative position,The main frame 18 of the bag holder is pivoted on the brackets 11 bymeans of pivot pins 14., cotter pins 15 being provided to retain thepivot pins in position. The pins 14- pass through suitable apertures inthe braclres 11 and througl'i slots 16 in the frame 13, these slotsbeing provided for a purpose hereinafter set forth. The rear ends of theframe 18 are rounded and made semi-circular as shown at 13, whereby theframe 18 may be lifted on the pins 14 to in operative position. Then theframe has been lifted to substantially vertical position the weight ofthe frame will cause it to drop to a position in which the pins 14 aredis posed at the opposite ends of the slots 16, from that in which thepins 14: are shown in Fig. 2 the frame thereby being retained in itsvertical or inoperative position. In order to again swing the frame tooperative position, the operator lifts the frame sufficiently toposition the pins 1 1 in the lower ends of the slots 16 and then allowsthe frame to fall to the position shown in Fig. 2.

The bag holding means in the present embodiment consists of a pluralityof pins 17 reciprocally mounted in clamping members 18 secured to theframe 13 in any suitable manner, as by rivets 19. The pins 17 areprovided intermediate their ends with rear- .wardly extending offsetportions or lugs 20 which are slidable in vertical slots 13 pro vided inthe frame 13 and these lugs pass through inclined slots 21 formed in aring 22 reciprocally supported on the frame 13 by means of pins 28. Thepins 23 pass through apertures 24 in the frame 13 and through slots 25formed in the ring 22.

As illustrated in Fig. 3, the upper portion of each of the slots 21 issubstantially horizontal as shown at 26, whereas the remaining portionis inclined downwardly as shown at 27. eating or rotating the ring 22,this means being embodied in handle 28 secured in any suitable manner tothe ring 22 in passing through a slot 29 in the frame 13. Cotter pins 30and suitable washers 31 are carried by the pins 23 and retain the pinsin place.

The improved bag holding means is manipulated in the following manner:In full lines in Figs. 1 to 4 I have shown the positions of the variouselements when the bag holding or piercing pins 17 are in operative Meansis also provided for reciproposition, or in position to hold the bag.When the bag has been filled to capacity and the operator desires torelease the bag, the handle 28 is manipulated, being moved in aclockwise direction (see Fig. 1) and through this handle the controllingring 22 is also moved to the dotted line position shown in Fig. 1. Asthe controlling ring 22 is moved to this dotted line position, the lugs20 carried by the pins 17 will be drawn downwardly by the inclinedportions 27 of the slots 21, and thus the pins will be withdrawn fromthe bag, releasing the bag.

The method of swinging the bag holder to inoperative position has beenalready described and therefore will not be further explained.

From the above description it will be seen that an exceedingly simpleand efficient construction has been provided for performing the desiredfunctions. and moreover, a construction which will firmly and securelyretain the bag in position to receive material, and a construction whichmay be manipulated with little effort to release the bag when desired.

While I have in the above specification described one practicalembodiment of my invention, it should be distinctly understood that I donot intend to be limited to the exact construction and arrangement ofparts illustrated and defined. Modifications may therefore be employedwithout departing from the spirit and scope of the invention asexpressed in the following claims.

1. In a bag holder, a frame, a ring positioned within said frame andconcentrically movable with respect to said frame, bag piercing meanscarried thereby, and means fixed to said frame and extending throughsaid ring for guiding said ring in its move ment in actuating saidpiercing means to operative and inoperative position.

2. In a bag holder, a frame, a ring ar ranged concentrically withrespect to said frame, vertically movable bag holding means carried bysaid frame, said means having lugs formed thereon and inclined slotsformed in said ring engaging said lugs for moving said bag holding meansto operative and inoperative positions.

3. In a bag holder, a ring positioned within said frame, reciprocablebag holding pins carried by said frame and slidable with respect to saidring and a controlling handle connected to said ring and through saidframe for guiding said ring and for controlling the actuation of saidpins.

4. In a bag holder, a fume, reciproeable bag holding pins carriedthereby, controlling means for said reciprocable bag holding pinsmovably mounted on said frame, and means carried by said controllingmeans and extending through said frame whereby said controlling meansmay be manipulated.

5. In a bag holder. a substantially circular frame, reciprocable bagpiercing means carried thereby, and a substantially circular controllingmember movably mounted on said frame and engaging said piercing meansand means for moving said piercing means by said controlling member tooperative and inoperative positions.

6. In a bag holder, a frame, bodily inorable bag holding pins carriedthereby and having laterally projecting lugs, bag controlling meanshaving inclined slots therein engaging said lugs, whereby said bagholding pins may be moved to operative and inoperative positions.

7. In a bag holder, a frame, reciprocable bag piercing means carriedthereby and having laterally projecting lugs, and a bag controllingmovable member positioned within and movable concentrically with respectto said frame, said member having inclined slots engaging said lugswhereby said hagpiercing means can be moved to operative and inoperativepositions.

8. A bag holder consisting of a support. a main frame secured thereto,bag piercing; pins mounted in said frame and vertically movable therein,a movable ring within said main frame having guide slots for said pins.said pins having lugs in said slots: meanconnected with said inner ringand passing through said main frame for rwiprocating said ring, andmeans connected with said main frame and extending into said ring forsupporting the latter in its reciprocatiinr movements.
